#### Matching is done as regular expression on full cell path
|

#### Example:
|

#### set xschem_libs { {/cmoslib/} {/analoglib/.*pass} buffer }
|
||||
#### in this case all schematic cells of directory cmoslib and cells containing
|

#### /analoglib/...pass and buffer will be excluded from netlisting
|

#### default value: empty
|

# set xschem_libs {}
|

#### noprint_libs is a list with same rules as for xschem_libs. This

#### variable controls hierarchical print
|

#### default value: empty
|

# set noprint_libs {}

#### nolist_libs is a list with same rules as for xschem_libs. This

#### this is the default:
|

# set initial_geometry {900x600}
|
||||
|
||||
#### if set to 0, when zooming out allow the viewport do drift toward the mouse position,
|

#### allowing to move away by zooming / unzooming with mouse wheel
|

#### default setting: 0
|
||||
# set unzoom_nodrift 0
|

|
||||
#### left corner. Default: 0
|

#### UNDO: SAVE ON DISK OR KEEP IN MEMORY
|

###########################################################################
|

#### Alloved: 'disk'or 'memory'.
|

#### Saving undo on disk is safer but slower on extremely big schematics.
|
||||
#### In most cases you won't notice any delay. Undo on disk allows previous
|
||||
#### state recovery in case of crashes. In-memory undo is extremely fast
|
||||
#### but should a crash occur everything is lost.

#### It is highly recommended to keep undo on disk.
